Abstract

Spiral polishing mechanism refers to the technology of applying a high-speed turning screw rod in the process of workpiece surface polishing. For the purpose of increasing the machining effect, a powerful ring magnet was installed around the workpiece. In this study, the new self-developed magneto-elastic abrasive would be used to polish the inner wall of the bore, the so-called workpiece surface, under the attraction of the surrounding magnet and the drive of the turning rod. The new magneto-elastic abrasive not only eased the polishing force by its flexibility but also avoided deep scratches on the workpiece surface. The control of machining parameters on surface roughness and material removal were discussed to look for the best combination of the parameters; at the same time, the effects of each parameter on the workpiece surface topography after the polishing were also examined. The results of the experiment indicated that magnetic flux density and magneto-elastic abrasive concentration affected the surface roughness the most. In addition, the newly developed magneto-elastic abrasive significantly improved the polishing effect of the workpiece surface, at the rate of 94 %.
